Scinax squalirostris is a species of frog in the family Hylidae. It is found in southeastern, southern and central Brazil, Uruguay, northeastern Argentina, southern Paraguay, and Bolivia. The nominal species might actually represent more than one species. Common names striped snouted treefrog and long-snouted treefrog have been coined for it.
Scinax squalirostris is a small species measuring 24–29 mm (0.94–1.14 in) in snout–vent length. The overall appearance is slender; the limbs are slender and the hind limbs are fairly long. The head is long and wider than the body. The snout is very elongated. The tympanum is distinct. The dorsal ground color is brownish. There is a narrow, black mid-dorsal line and black canthal lines bordered with white. Two black stripes start from the eye and enclose a white or flesh-colored area. The belly is greenish yellow. The vocal sac is large and lemon-colored.
Scinax squalirostris occurs in open areas of grasslands, rushes, and Eryngium spp., but also in forests, at elevations below 1,500 m (4,900 ft). Breeding takes place in small permanent and temporary waterbodies, including cattle ponds.

Rare
Under 5% of wildlife watchers report a Striped Snouted Tree Frog sighting in Buenos Aires on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, August–September and November
In those months about 10% of wildlife watchers report a Striped Snouted Tree Frog in Buenos Aires on a given day, against under 5% in April–July, October and December–February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Striped Snouted Tree Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Striped Snouted Tree Frog sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Striped Snouted Tree Frog is recorded against all the amphibians logged in Buenos Aires (21 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
